I like number 3.

Very cool WaltzElf!
I'll not lie - that's my favourite too

. On the day of the shoot - we hadn't actually discussed that costume, and my partner comes out of the change room in her underwear and my exact words were - "um, you missed something." Then I felt rather stupid
On a more serious note - I highly recommend anyone in a close dance partnership go get some photos done. Don't go to a glamour photographer - you'll pay a fortune more than you need to. You're better off doing a google search for an independent studio photographer, or even a final-year photography student looking to build a portfolio in your area.
It won't be nearly as expensive as you might imagine (my partner and I got 100 photos out of our shoot, and it cost us a grand total of $650 Australian, which included make up and studio space).
The result is you'll have some nice photos to remind yourself of the partnership better than "on the comp floor" photos ever will, and the 4-5 hour long photo shoot, and getting the costumes organised together, and the whole process in general is just so much fun.
The downside is - every time I see these photos I realise I really miss that partnership :-?
